On the face of it, no, but as you read through the article both sides of the "Yes/ No" coin are argued well...

However, the most telling paragraph of the whole article comes just before the end; where the writer sums up exactly how you should feel when you encounter failure, in whatever form that may be:

"Don’t beat yourself up about it. Don’t overly introject this as a failure that is a representation of your value and worth as a person. Your life and your career are not defined by this. But do be disappointed. Do be frustrated. Do seek to understand what happened. Do seek to know if you could develop your management and leadership. Do seek to learn from this experience."

Keeping this in mind might just lead you on the road to success.....

Of course there is a big, big difference between taking it personally and not being able to manage your boundaries. There is a distinction between having passion for your job and attaching so much self-worth to it that you are not able to protect yourself psychologically, where every mishap and mistake is taken so personally that it penetrates the core of your self-esteem. If work becomes too dominant a part of your identity, that can also be dangerous.
There’s an appropriate happy medium to be found, a place somewhere between workaholism and anaesthetising the spirit.
